gojenkins VS gval

Next up, I was looking into the the gojenkins client library to see if there were some built-in methods to allow me to do my own API token management and rotation to solve the issue above. And of course, it didn't exist. It was at this point I sat back and thought, "Really? No one has yet to implement a decent solution for managing Jenkins tokens/users yet? This is the most widely used CI server out there. Surely it has to exist..."

For practical start, see this: https://www.youtube.com/watch?v=JiViND-bpmw It explain one particular type of parser type that is quite easy to grasp and fun to write. Also look on some libraries that deliver "expression executors" - these are in fact small interpreted languages and can give you plenty of examples. Classic one (though currently unmaintaines I think) is: https://github.com/PaesslerAG/gval but there are plenty more, just google for them. On my last words, this is very enjoyable part of programming but it requires much learning so be patient and have fun!

There is a nice lib that let you write much more compact expressions https://github.com/PaesslerAG/gval I'm using this lib for evaluating expressions in a small BPMN engine. At least your solution is missing a context, functions and data to work on. But trying stuff out is propably the best way to learm Go!
